A Nocturne is usually a musical composition that is inspired by, or evocative of, the night.
The name Nocturne was first applied to pieces in the 18th century, when it indicated an ensemble piece in several movements, normally played for an evening party and then laid aside.
Nocturnes are generally thought of as being tranquil, often expressive and lyrical, and sometimes rather gloomy.
